Ethernet carries 10 mbps. 100BASE-FX 100-Mbps baseband Fast Ethernet specification using two strands of multimode fiber-optic cable per link. To guarantee proper signal timing, a 100BASE-FX link cannot exceed 400 meters in length. Based on the IEEE 802.3 standard. See also 100BASE-X, Fast Ethernet, and IEEE 802.3. 100BASE-T 100-Mbps baseband Fast Ethernet specification using UTP wiring. Like the 10BASE-T technology on which it is based, 100BASE-T sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BASE-T. Based on the IEEE 802.3 standard. See also 10BASE-T, Fast Ethernet, and IEEE 802.3. 100BASE-T4 100-Mbps baseband Fast Ethernet specification using four pairs of Category 3, 4, or 5 UTP wiring.

See also Fast Ethernet and IEEE 802.3. 100BASE-TX 100-Mbps baseband Fast Ethernet specification using two pairs of either UTP or STP wiring. The first pair of wires is used to receive data; the second is used to transmit. To guarantee proper signal timing, a 100BASE-TX segment cannot exceed 100 meters in length. Based on the IEEE 802.3 standard. See also 100BASE-X, Fast Ethernet, and IEEE 802.3. 100BASE-X 100-Mbps baseband Fast Ethernet specification that refers to the 100BASE-FX and 100BASE-TX standards for Fast Ethernet over fiber-optic cabling.
